I'm aware of the NCIS scenes, what else you guys got?

Kingsman

Training scene where they shove a shower hose down a toilet and use it to breathe...

There would be no air (or even sewer gas) to breath in that case. Toilets work by raising the water level in the bowl above the water level in the S-bend/siphon. Since the room was full of water, those toilets would have been flushing constantly, and the whole pipe would be full of water.

Better(ish) solution. Use the body bags that they each had to fill out and place in their trunk/locker to capture an air bubble. That would at least give you some time to attack the door, or figure out how to drain the room.

Maybe the constantly flushing toilet would drain the room.

We just watched "The Trap" last night. There was a major pop concert that ended in time for family dinner time during daylight. In the concert, they were depicted having time to make multiple trips to the merch tables and concessions, and in one of those trips, they talked like it was an intermission to change the stage set between songs.

There’s a scene in Spider-Man: No Way Home where Tom Holland is fighting the Green Goblin. Goblin grabs Spidey, jumps with him, and then they both smash through the 23rd or so floor of the apartment building they’re in and they land on the floor below.

Sure, they’re both super strong but neither of them used their strength to push through the floor. They just jumped and reached no more than like a foot off the floor, implying that gravity pulled them both through the floor. Okay, so the floor was built poorly, but then why did falling 10+ feet from the 23rd floor to the 22nd floor not make them smash through the 22nd floor?

That movie’s a lot of a fun but that scene makes me upset lol

Sprinklers react to heat, not smoke and they don't all go off at once. Also the water that comes out is brown from rust, not clear.

War bows are so heavy that you can barely hold it for the moment it takes to aim. There's no way you're holding it for minutes before told to release.

Fire sprinklers have two requirements: to be able to turn on immediately if they're ever needed, and to dispense something capable of extinguishing a fire. In order to accomplish this, the pipes that feed them are constantly, 24/7, full of water, providing constant pressure on the sprinkler head to be ready to feed it with water in case it ever needs to go off. These water pipes are generally not used for anything else, so the water does not tend to circulate. In fact, there's usually a sensor in them that detects if the water is flowing (and thus if any sprinklers have been triggered, providing somewhere for it to go) and activates the building's fire alarm. When a fire sprinkler goes off, the water that comes out has been sitting in that pipe (an iron pipe if you're lucky, a lead pipe if you're not) basically since the building was built.

That stuff is NAS-T.

[-] ContrarianTrail@lemm.ee 3 points 4 hours ago

When replacing thermostat valves or radiators in buildings with steel-pipe radiator lines, the water that comes out is often as black as ink. It’s surprising how dark it can get.

And for anyone wondering why steel is used, yes, it does rust, but only while there’s air in the water. As the pipes start rusting, that air gets used up, and the rusting stops. Same applies to sprinkler lines. Steel pipes in radiator lines can easily last the building’s lifetime, whereas copper pipes for drinking water usually need replacement every 30 years or so.

[-] Agrivar@lemmy.world 1 points 3 hours ago

Copper pipes only need replacing that often if a) you cheaped out on construction and used the thinnest kind (M-type, which isn't even legal in some states), and b) you had some pressure issue along the way that left the pipes only partially full of water for a time.

I think a good common one is explosions that throw people at least 10 feet without killing them. If the shockwave is strong enough to do that, isn’t it strong enough to tenderize and completely disable all of your internal organs as well?

[-] AA5B@lemmy.world 8 points 7 hours ago

Plus if it’s military, it’s usually the shrapnel that kills you, not the shockwave. Fuel-air devices are a different story

When something or somebody is injected into space, they always freeze in seconds. The logic is that "space is cold" but space is mostly a vacuum and vacuums don't have temperature. Vacuums insulate against conduction, so you're not going to freeze anytime soon. (You'll lose heat via radiation but that will take a while).

Not to mention the effect that zero pressure has on freezing/boiling points. If anything you'd be steaming as all the water on you evaporates!

[-] Saleh@feddit.org 23 points 9 hours ago

The evaporation cools the remaining stuff down. And steam is not visible. What we consider visible "steam" is fine liquid water dropplets suspended in air, as the saturated air cooling down demands for some of the water to become liquid.

So you can be steaming and freezing at the same time.

Where in countless mystery/thriller stories bad guys arrange meets in huge open deserted buildings, to be uninterrupted. In the real world, the place will securely locked and gated, or multiple houseless people will have already moved in there.

Electrical shocks applied to asystolic hearts to restart them is a classic.

The shock serves to stop fibrillation and to induce a rhythmic firing of the neves, that's why it's called defibrillation. Fibrillation is random firing of the nerves, asystole is no firing.

If I recall correctly my father told me you use an injection of adrenaline for asystolic hearts. Kind of like in Pulp Fiction. Though I think injecting directly into the heart isn't the preferred method anymore.

[-] cactopuses@lemm.ee 2 points 4 hours ago

I watched a show talking about adrenalin and injecting it into the heart, the doctor was saying how it would be the worst place to try and go first because damage but also because you'd be more likely to hit a rib or puncture a lung then actually make it through the heart.

I always think its funny how bullets never seem to penetrate anything in movies. Like, guy hiding behind a barrel? Nope, cant penetrate, even with a rifle. The newest Batman movie had me shaking my head as he shrugged off multiple rifle rounds to his armor.

Bullets are insanely dangerous and powerful. A .223 round can penetrate a solid brick wall pretty easily, and can destroy a cinderblock wall with some effort. Even if it doesnt penetrate, the amount of force applied is incredible. Plates designed to stop bullets have to be made in specific ways to make sure a bullet doesn't penetrate, but even with that plate, the sheer force of an impact can break bones.

Okay, so if we are going to give batman flack for having super-alloys, where do we stand on Tony Stark putting a reactor in his chest with no concernable heat sink. (He wears it without the suit)

[-] cynar@lemmy.world 4 points 6 hours ago* (last edited 6 hours ago)

Simple, stark is a semi latent technomancer. His arc reactors might actually work, but the mini ones don't. They are effectively conductors for magic. They turn magic into electricity with zero heat output. This also explains the suits momentum damping capabilities, and why they can't be copied easily.

So many movies show people getting into gun battles indoors, and they will jump behind a couch or flip over a coffee table and take shelter from a hail of bullets, like that thin furniture is going to stop anything.

[-] BehindTheBarrier@programming.dev 4 points 6 hours ago

Just got reminded of the silencer gun battle scene in one of the John Wick movies. That was perhaps the most unrealistic thing I'd seen in those.
